A cantenna can be used as a satellite dish feed horn. The 5.5 GHz cantenna dimensions are almost perfect in that they make a good fit for the standard TV satellite dish. The resulting setup is a low-cost high-quality high-gain antenna. [6] Such setups are widely used in wireless community networks for long-distance Wi-Fi links.
The WokFi antenna is considered simpler and cheaper than other home-built antenna projects (such as the popular cantenna), but is a very effective method to boost the Wi-Fi connection quality, audit access point coverage, and even quickly establish WLAN viability – perhaps if a more professional setup is eventually intended.
Wi-Fi over Coax is a technology for extending and distributing Wi-Fi signals via coaxial cables. As an in-building wireless solution, Wi-Fi over Coax can make use of existing or new cabling with native impedance of 50 Ω shared by a Wi-Fi access point , cabling run, and antenna.
A coaxial antenna (often known as a coaxial dipole) is a particular form of a half-wave dipole antenna, most often employed as a vertically polarized omnidirectional antenna. History [ edit ]
A short antenna pole next to a house Multiple Yagi TV aerials. Antennas are commonly placed on rooftops and sometimes in attics. Placing an antenna indoors significantly attenuates the level of the available signal. [19] [20] Directional antennas must be pointed at the transmitter they are receiving; in most cases great accuracy is not needed ...
Also called a low-noise block, [1] [2] low-noise converter (LNC), or even low-noise downconverter (LND), [3] the device is sometimes inaccurately called a low-noise amplifier (LNA). [ 4 ] The LNB is a combination of low-noise amplifier, frequency mixer , local oscillator and intermediate frequency (IF) amplifier.
